How to mix material and texture to single mesh?
As far as I know you can only mix textures/materials in one "material".
Try this:


Assigne all verts to "Material.001"
Copy "Material.004" and add it to "Material.001"
UV unwrap your object
Copy nodes (see the image below)
Set "image texture" to clip and to non-color data
Match UV Unwrap to your texture
